@TomBrossman sorry don't know, how do I do it?

Can you please try the answer there and see if that fixes it? You need to press Ctrl + Alt + T, then type gksu gedit /etc/apt/sources.list and put a # in front of line 60.

@TomBrossman should I post the sources list?

You can if you like. Why not try the solution first and see if it works? No need to carry on with editing the question if you have an answer already.

@Erikson What didn't work? If you deleted lines 59 & 60, you can't see that same error about line 60 you had before. If you have a new or similar problem try searching for an answer here, then post a new question if you still have an issue that hasn't been posted already. You can also try asking in chat for help.

@Erikson Also, looking at all your questions posted recently I see a common thread, they all involve typing mistakes in your list of software sources. Since you've only had Ubuntu installed a few days it might be easier to just do a clean reinstall to address these (and any other) mistakes. If not, Mik's answer here is probably the clearest explanation so far. Remember, every letter (and space) are important, they have to be 100% correct. Good luck!
